LANSING, MI — A Lansing Police Department detention officer suspended and charged for allegedly assaulting an inmate last month will stand trial in several weeks.

David Gladstone, a 20-year-veteran of the department, was placed on paid administrative leave after being formally charged on March 22 with misdemeanor assault and battery. He is set for a jury trial before Lansing District Judge Charles Filice on May 20, court records show.

"All allegations or complaints against department members are taken seriously and thoroughly investigated," Lansing Police Chief Teresa Szymanski said last month. "The allegation against D.O. Gladstone in this matter is disappointing and if the allegation is found to be true, it will not be tolerated by the Lansing Police Department."

The LPD Internal Affairs Unit also is investigating the incident and will determine whether Gladstone violated the department's policies and procedures. He faces disciplinary action ranging from counseling to firing.
